Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

OxidOS Automotive
Hi! This is Daniel from OxidOS Automotive (stating this for disclaimer purposes).
Yes, our OS is based on TockOS, and our CEO (Alex Radovici) is #7 in the contributors list (https://github.com/tock/tock/graphs/contributors), with other colleagues contributing in the past years.

Safety vs. Performance. A case study of C, C++ and Rust sort implementations
I'm definitely not the best person to answer this, but honestly it's not bad. Here's an example of a moderately complex peripheral, the cortex-m MPU, and how one rust OS handles it:
https://github.com/tock/tock/blob/3a0527d586702b8ae8cb242391...
Reads and writes turn into volatile reads, so everything works out under the hood. You get the benefits of everything having good names, declared sizes, and proper typing on your register accesses. You can extend that to bit accesses as well.
Rust still has a few areas it isn't competitive in, like your hyper limited or obscure chips (e.g. 8051s, XAP), mature tooling around formal methods, and a certification story for safety critical code. People are working on these latter two issues (e.g. ferrocene) and supposedly very close to public delivery, but you know how slow the industry is to adopt new things even then.

Real-Time Operating Systems 101: Basics for Efficient Computing
There's Tock (https://www.tockos.org/), which is written in Rust (with sprinkles of assembly).
-
Unwinding the Stack the Hard Way
Yeah, and I like I mentioned in the earlier comment, omitting the frame pointer reduces code size by 10% on RISC-V targets, which is huge when dealing with embedded flash: https://github.com/tock/tock/pull/1660

Embedded real time OS
Tock is an excellent embedded OS written in Rust and has some good industrial support. I think Tock gets a lot of stuff right and I highly recommend some of the talks the developers gave on it.

Fedora now has frame pointers
Unfortunately, it increases the code size by 10%. I was looking into this just last week, and can confirm that it's still a problem on the latest version of Rust nightly: https://github.com/tock/tock/pull/1660
I wish we could have frame pointers, because they would make working in embedded land so much easier and more reliable, but a 10% increase in code size just isn't worth it.

Implementing TCP in Rust
There is also the Rust TCP/IP stack https://github.com/smoltcp-rs/smoltcp which is not mentioned as reference (and it's probably more useful to have a look there than querying ChatGPT).

Create TCP connection with Pnet
Trying to dig out a link for you, will edit when I find it; TCP and Layer 4 raw sockets do not play nicely together on many platforms. You’ll probably have to send at the datalink layer and/or use something like https://github.com/smoltcp-rs/smoltcp

Introduction to TCP and Sockets
This seems close to what you're asking for: https://github.com/smoltcp-rs/smoltcp
A small-ish tcp/ip stack, in rust.
- smoltcp is a standalone, event-driven TCP/IP stack that is designed for bare-metal, real-time systems. Its design goals are simplicity and robustness.

Kerla: Monolithic kernel in Rust, aiming for Linux ABI compatibility
This here is a kernel including a memory-safe TCP/IP stack (https://github.com/smoltcp-rs/smoltcp/), and not having it crash or be full of security vulnerabilities due to preventable memory corruption is a quality beyond personal language preferences.

Let's suppose for a minute that I've COMPLETELY lost my mind
Oh, and you also probably want to check out smoltcp, a userspace/"no operating system required" networking stack that we often use in embedded rust.
